2001 Lexus LX 470FACTORY OEM SERVICE PROCEDURE

Panic Mode Function

WARNING: This page is about a different car, the 2002 Lexus LX 470. However, it is still accessible from the selected car via links, so may be relevant.

When the panic switch on the transmitter is pressed, the wireless door lock ECU receives a signal and enters the panic mode. The signal input into the theft deterrent ECU from the wireless door lock ECU turns on the theft deterrent horn, and flashes the taillights and headlights. When the panic switch or the unlock switch of the transmitter is pressed during the panic mode, the panic mode is canceled, and the theft deterrent horn stops, and the taillights and headlights are turned off.
